Why is it a tragedy?

=3. I wanna know why it's a tragedy before I read it. I dislike tragedies.

Spoiler (mouse over to view)

Please try to get as quick info as you can with minimal spoilers... Like - "X's family dies", "Y dies", or "W dies but is later cloned (or otherwise re-born)" INSTEAD of "AFTER A FIERCE BATTLE WITH THE OVERLORD Z LOSES ALL OF HIS POW--" yeah I want to actually read the story for that part xD

Some characters die, but not necessarily enough to categorize this as a tragedy. Certain events are rather tragic (especially the backstory of some of the characters) but I don't think that any of that should keep you from reading. This series actually has a much happier ending than I was expecting.

I agree with Alaena, it's definitely worth the read in spite of the iffy tag. I think the companion series Touhou Shinigami is more deserving of being labeled as a tragedy, but it's still really sweet.
